i have a 1990 rx7 and when i drive my inside of the car sometimes smells like gas do i have a leak or is it something else or is just normal and also whats gas fast .

 

From what i've read it could be the pulsation damper. But I smell gas in my car, but not very often, and not very dense. I blame my smell on my catalytic converters because they are clogged.

 

If the smell is strong under the hood, take a flashlight and look under the upper intake manifold for a puddle of gas. If you see one, do not drive the car until you replace the pulsation damper (PD). The PD is integrated with the primary fuel rail, BTW.
